Abstract

The dataset contains experimental fits for various benzofuran-Rg clusters. Specifically, it includes data from experimental fits of benzofuran - Ar, and benzofuran -Kr clusters, derived using the SPFIT/SPCAT programs from rotational spectra measured in the 2 – 20 GHz frequency range. For some clusters, isotopologues of the molecular complexes in natural abundance are also included. The benzofuran - Rg clusters exhibit intriguing structural features, as they represent prototypical aggregations of aromatic rings that interact with rage gas.
